Tank-type-variable single-tank water pump pulley

Abstract

The invention relates to an improvement on a cooling water pump of an internal combustion engine and discloses a tank-type-variable single-tank water pump pulley which is provided with a body, and a cylindrical spoke is arranged in the middle of the body. The tank-type-variable single-tank water pump pulley is characterized in that an annular tank-type-variable triangle belt chute is formed in the right end of the cylindrical spoke; screw holes are formed in the middle of the cylindrical spoke; the cylindrical spoke and the body are cast into a whole; the triangle belt chute is composed of a chute left disk and a chute right disk; the chute right disk and the body are cast into a whole; the front end of the chute left disk is provided with a cylinder mounted at the outer side of the cylindrical spoke; three groups of holes corresponding to the screw holes are formed in the cylinder, and the axial spacing distances among the three groups of holes are sequentially 4mm and 5mm; and the chute left disk can be fixed on the body by using bolts through any one group of holes in the three groups of holes, so that the tank type of the water pump pulley is varied among three tank types A, B and C. The tank-type-variable single-tank water pump pulley has the beneficial effects that different demands of different internal combustion engines for tank types are met, and the energy saving and consumption reducing effects are achieved.

Description

technical field [0001] The invention relates to the transformation of a cooling water pump of an internal combustion engine, which is a single-groove water pump belt pulley with a changeable groove type. Background technique [0002] At present, the pulley grooves of cooling water pumps for internal combustion engines generally use three groove types: A, B, and C. In actual work, it is often necessary to use fixed single-groove pulleys of different groove types to assemble the same water pump to meet the different needs of internal combustion engines, which brings a lot of inconvenience to production management. and material waste. Contents of the invention [0003] In order to solve the above problems, the present invention provides a single-groove water pump pulley with a changeable groove type, which can change the groove type according to the requirements of different internal combustion engines. [0004] In order to achieve the above purpose, the technical solution a...
